Step 1:
You want to find how many calories are in one pretzel.
192 / 12 = 16
So there are 16 calories in each pretzel.
Step 2:
Multiply 16 to 15 to find how many calories are in 15 pretzels.
16 x 15 = 240
--------------------------------------------------
Answer:
You will consume 240 calories if you eat 15 pretzels.
